7 Claims.

This invention relates to new and useful improvements in an air cooling wave device.

More specifically, the invention proposes the construction of a device as mentioned which is characterized by a casing having a slotted side wall and slotted end Walls. It is proposed that driven propellers blow air into the casing through the end walls. A certain new construction is proposed within the casing for deflecting the air out through the slotted side wall.

It is proposed that the new construction within the case be so designed that the emerging air comes out in predetermined waves.

More specifically, the invention contemplates an air cooling device as mentioned which may be conveniently suspended from a ceiling, or mounted on a wall or other support, and which will blow the air laterally instead of directly forwards.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevational view of an air cooling wave device constructed in accordance with this invention.

Fig. 2 is an enlarged bottom View looking in the direction of the line 2-2 of Fig. 1.

Fig. 3 is a vertical sectional view of the Wave device.

Fig. 4. is a horizontal sectional view taken on the line l-d of Fig. 3.

Fig. 5 is a perspective view of one of the small deflectors used in the device.

Fig. 6 is a similar view to Fig. l, but illustrating another form of the invention.

The new air cooling device, according to this invention, includes a casing it] having a slotted side wall H and slotted and slightly flexible end walls l2. A tube it extends centrally through the said end walls iii. A shaft I4 is rotatively mounted through the tube It. Propellers I5 are removably mounted on the shaft Hi outside of said end walls [2 and are for the purpose of blowing air towards each other and through the slots of the end walls [2 into the casing ll].

An electric motor It is connected with the shaft id for driving the propellers [5. A deflector i7 is fixedly mounted within the casing Ill and has curved faces l8 facing the end walls l2 deflecting the air which is blown into the casing 50 laterally out through a central zone of the side wall ll of the casing It. A plurality of small spaced deflectors is are mounted on the curved face 18 of the said deflector I1 and are for the purpose of guiding some of the air through end zones of the said side wall ll.

Preferably, the casing I0 is constructed of sheet metal. The end walls l2 are in the nature of covers which are removably mounted on the side wall ii. The deflector I1 is hollow and preferably made from sheet metal. It is formed with radial slots 20 at points beneath the small deflectors l9. Each small deflector I9 is also constructed of sheet metal and has a bar portion 2| across its back face. A pair of headed studs 22 is mounted on each bar portion 2i and slidably engage through the slots 2t. An inner member 23 of substantially the same shape as the deflector I9 is mounted on the deflector l! and frictionally engages the heads of the studs 22 for holding them in fixed positions.

This inner member 23 is formed with a plurality' of radial slots 25 dividing ofl apex-like sections 26 which have a certain resiliency because they are thus free. These apex-like sections Zli are normally clamped down tight. The tube I3 is provided with flanges 21 engaging the points of the apex sections 26. Nuts 28 are threadedly engaged on the ends of the tube l3 and when turned tight, flex the walls l2 and similarly flex the adjacent portion of the deflector ll and so grip and engage the apex-like portions 26. The deflector I7 is supported by brackets 28 extended through one of the walls 12 and attached upon the motor [6.

The operation of the device is as follows:

The motor It drives the propellers 55 which blow air through the slots of the end walls l2 into the casing Ill. This air strikes the curved faces N3 of the deflector l1 and travels along the curved faces to the periphery of the deflector ll. From the periphery the air passes out through the central zone of the side wall I I. Some of the air which travels along the facesl8 of the deflector I1 is further deflected by the small deflectors l9. This air is deflected so as to pass through end zones of the side wall I l.

The area of discharge of the air through the sidewall H may be controlled by shifting the positions of the smaller deflectors it, To do this, the nuts 28, the propellers l5, the end covers H! are removed from the side wall H, exposing the small deflectors I9. shifted now along the slots 20 because when the nuts 28 are removed the apex portions 26 of the inner member 23 became free. When the parts are reassembled and the nuts 28 are tightened, the apex portions 26 will be clamped down again, and the member 23 will frictionally engage the heads of the studs 22, holding the small deflectors (9 in adjusted positions.

The propellers l5 may also be within the end walls I 2' as shownin Fig. 6 and with dot and dash lines in Fig. 3, so that the air current may be sucked in by the propellers through the openings of the end walls [2' and forcedagainstthe The deflectors is may be .fixedly mountedjinsaid ferred embodiments of my invention, it is to be understood that I do not limit myself to the pre- 'cise constructions herein disclosed and the right is reserved to all changes and modifications com- V ing within the scope of the in the appended claims.
